- In the comic strip Blondie, Dagwood constantly eats comically large sandwiches. He's so well known for it that his name has entered the dictionary meaning "a thick sandwich filled with a variety of meats, cheeses, dressings, and condiments", and he's the Trope Namer for that type of sandwich. It's also a popular name for sandwich shops in the midwest. In Belgium, Dagobert (the French name for Dagwood) is the name of (thick) sandwiches made from a half French bread filled with lots of ham, cheese, salad, tomatoes, carrots, mayonnaise and sometimes onions.
